David Evans used to be a consultant to the Australian Greenhouse Office. He spent six years with the Australian government building models about the influence of carbon emissions on our atmosphere. This was the Aussie who wrote the carbon accounting model that measures Australia's compliance with the Kyoto Protocol.
Well .. guess what Dr. Evans is saying today? Since he started working in the office in 1999, "new evidence has seriously weakened the case that carbon emissions are the main cause of global warming." By the year 2007, the evidence is conclusive: carbon played only a minor role in recent global warming and was not the main cause.
Dr. Evans put together some basic facts for the public and government officials in regards to global warming. Here is just a taste.
1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it.
2. There is no evidence to support the idea that carbon emissions cause significant global warming.
3. The satellites that measure the world's temperature all say that the warming trend ended in 2001, and that the temperature has dropped about 0.6C in the past year (to the temperature of 1980).
4. The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. Which says something important about which was cause and which was effect.
Keeping that last point in mind, Al Gore still preaches in his movie that the ice cores are the sole reason for believing that carbon emissions cause global warming. Dr. Evans says, "In any other political context our cynical and experienced press corps would surely have called this dishonest and widely questioned the politician's assertion."
So instead, what do we get? The world has spent $50 billion on global warming since 1990 and yet there is no evidence that carbon emissions are actually causing global warming! It's a fraud. A fraud to enrich Gore, and a fraud designed to form the basis for repeated attacks on capitalism and free market economies.
Would someone out there please wake up?
